Enhancing the Performance of Solar Refrigeration System

Sanchit Kumar Gupta

Abstract: This paper present the possibility of enhancing the performance of Solar refrigeration system using Terracotta and Peltier effect. Thermoelectric modules are the key elements in this refrigerator for providing the thermoelectric cooling. The one side of the thermoelectric module gets cooled and provide refrigerating effect while the other side becomes hot and rejects the heat to the environment with the help of fans and fins. It will evidently reduce the burden on our ecological system by reducing the pollution caused by CFCs and other toxic components. By experimenting for 30 min every day for 12 days and the measured ambient temperature between 300C-380C; there is a significant decrease in the temperature inside the cabinet and it is measured between 250C-340C. The coefficient of performance so get after performing the test is between 0.2054-0.3547. The average coefficient of performance of the system was 0.3202 and there was a temperature difference of average 50C between ambient temperature and the temperature inside the cabinet.
